l pplication filed December 5, 1888. Serial No. 292,728. (No model.)

To all whom t may concern,.-

Be it known that I, THOMAS FLYNN,of the city, county, and State of New York, have invented certain new and useful Improvements in Paper-Box Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereommakiug a part of this specification.

My invention. relates to machinery for the manufacture of paper boxes; and it consists in the n ovel combination and arrangement of the several operative parts of a machine for pasting, folding, and forming a suit-able paper or card-board blank into a nished box, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of myimproved machine 5 Fig. 2, a central vertical section in line os sc of Fig. 1; Fig. 3, a transverse vertical section in line y y of Fig. 1; Fig. 4, a detail, in perspective, of the lower clamping-frames closed together; Fig. 5, a similar detail of aportion of the top of the table, illustrating` the form of the folding-aperture therein and the movement of the edge-closing slides and pins, one of said slides being removed; Fig. a plan view of the paper blank ready for folding; Fig. 7, a perspective View of the blank when partly forced down into the folding-aperture, whereby the folding in of its ends and sides is initiated; and Fig. S, a view in perspective of the folded box complete as delivered from the machine.

Similar letters indicate like parts in all of the figures. i

A A represent the iframe-work supporting the operative parts of the machine, and ll the table over which the paper blank is carried to the folding-aperture.

C is the folding-aperture, whose length corresponds to that of the bottom of the box to be formed and whose width is somewhat greater than that of the box. The two end walls a d of this aperture are beveled, as shown in Figs. 1 and 5, to facilitate the folding in of the wings of the blank to be carried down through it.

D is a plunger whose form and dimensions correspond with those of the interior of the `two vertically-moving standards E E', (see Fig. 3,) adapted to reciprocate in suitable ways on either side of the table B, and which are actu ated by means of eccentrics F F on a transverse rotating vshaft F, mounted under the table and geared to a prime motor.

S S are slides mounted to reciprocate horizontally in suitable ways b l), formed in the top of the table B at each end of the forming-aperture C, as shown in Figs. 1 and 5. The inner end of each slide S is fitted with two spri 11g-actuated yielding pins T T of unequal length, the shorter pin T being made to project at about the middle of the end and the longer pin T between it and the farther side of the opening in the direction in which the blank moves. These slides are simultaneously forced inward to bring their ends and the pins projecting therefrom against the blank at the moment the blank is doubled up into the aperture C by the descent of the plunger by means of two fingers U U, dependent from the cross-head E of the plunger, and which terminate in enlarged beveled ends )V 1V, which are made to bear against the outer ends of the slides to move them, the return of the slides when the plunger moves up being automatically produced by means of springs 1l L', (see Fig. 3,) attached to the slide.

The plunger D,when lowered so as to project down through the folding-aperture C, is clasped between two clamping frames G G', (see Figs. 2, 3,and 4,) made to reciprocate horizontally immediately under the table, so as to close from opposite directions upon the plunger to embrace the same, the sides of the one frame G being made to overlap those of the opposite frame G as they come together, as shown in Fig. et of the drawings. 'lhcse two clamping frames are severally mounted upon horizontal bars G2G2, (see Fig. 2,) sliding in suitable ways, and are actuated so as close simultaneously over the plunger in synchronism with its descent through the folding-aperture C by means of eccentrics H H upon transverse shafts-lil Il', mounted to IOO rotate in the fra-ine below the level of the table parallel with the shaft F', te which they are severally geared.

The blank X (see Fig. (i) to be folded is fed forward over the table I3 and delivered in proper position over the folding-aperture C by means of parallel pairs of tapes or endless belts I I and I' I', carried over rollers JJ J' J', arranged in pairs and mounted so as to bring their points of contact on a level with the top of the table, as shown in Figs. l and 2. These rollers are all geared mediately to the shaft F' by aff-rain of wheels F2, (see Figs. l and 3,) to rotate in unison and in synchronism with the movements of the plunger, their movement being arrested while the plunger enters the foi-ming-aperture C and until it clearsthe same by means of an interrupted gear-wheel K, (see Fig. 1,) interposed in the train connecting the rollers with the shaft F. The tapes in each pair are placed in position to engage the central portion of the blank.

A stop Bis formed on the outerend ot' the table to arrest the blank so soon as it is properly in register over the forming-aperture C.

The guniming device consists of the gumming-pads L L, secured to a cross bar or head L', which is mounted to project transversely over the table, and tapes from a vertically-reciprocating standard L2, fitted in suitable ways on one side ofthe table and actuated by an eccentric on a shaft M, geared mediatcly to the shaft F. (See Fig. The gumming-pads L L are adapted to coat the lateral folds d d of the blank X with the paste or glue as they are brought into con tact therewith by the dropping of the cross-head L. They are freshly coated with the paste or glue after each movement of the cross-head by means of a traveling roller l), made to reciprocate back and forth under the gumming -pads when they are elevated. This roller is mounted on pedestals Q Q under the two ends of the cross-head L', these pedestals being formed with horizontal ways t, (see Fig. 2,) in which the ends of the roller travel freely, and the roller is carried back and forth therein while the cross-head L' is in its elevated position by :means of a connecting arm N, pivoted to an eccentric N', (see Fig. 1,) geared mediately to the shaft F. )'Vlien at rest, the traveling roller I) brought into contact with a feed-roller R, mounted in a paste-vessel R', and which operates to transfer the paste therein to said roller I). This feed-roller R may be geared inediately to the driving-shaft F', to be slowly turned thereby.

In the operation of the machine the blank X, cut in proper form, substai'itially as shown in Fig. G, is fed in between the rollers J and J and the upper and lower endless tapes Iand I', which pass around said rollers, and extend thence over the rear end of the table B. The blank X, caught and held between the tapes, will be carried forward by them until the lateral wings d d' of the blank are in register with the gumming-pads L L, when, by reason of the interrupted gear-wheel K in the train by which the tape-rollers J J and J' J' are driven, the further movement of the blank is arrested until the gumming-pads have descended into contact with said lateral wings d (l of the blank and rise to clear the same. In the meantime, while the one blank is thus brought to a standstill and gum med, the blank nextin advance is forced down by the descent of the plunger D through the forming-aperture C. The plunger bearing upon the portion Z of the'b'lank designed to constitute the bottom of the box presses it down into the aperture C. (See Fig. 7.) As it is carried down, the side wings or flaps c c of the blank, which are free from glue, will, by reason of the contact therewith of the longer pins T' T' of the two slides S S, which are forced inward as the plunger descends by the operation of the ends IV IV of the fingers U U, be turnedin against the plunger as the end itself is turned up. The gu nimed en d flaps d d will next be turn ed in against the outside of the side flaps e c by the pi-ns T T, and finally the guinmed side flaps d (Z will be turned in by the ends of the slides S S against the end flaps (l d and side flaps c e, the folding in of the iaps being assisted by the beveled walls a a of the aperture C and by the continued movement of the plunger. lYhen the pins T and T have carried the folded iiaps against the plunger, they yield to permit the continued advance of the slides which carry them. Thus, while the sides are folded in, the iiaps which form the ends of the box are turned in and made to overlap with their gum med faces superimposed in proper order, and being thus folded in upon the plunger are carried vdown below the table and caught between the clampingframes Gry G', which operate to press them firmly together to fix them and perfect the form of the iinished box. So soon as the box is thus pressed the frames open, the plunger vmeantime under the gumming-pads to recharge them.
